Recently I got an iPhone and was glued to it. I was truly amazed by its features and eye candy interface. I was searching for various kinds of tutorials, themes, apps, games, etc. Well, there was a lot of stuff over iTunes but the problem is we can’t buy it straight away without knowing how’s it, and whether it’s worth it.
